Hier kommt man mit wesentlichen Rechenoperationen aus. Das ist bei Unbekannten ein optimales Ergebnis, ist aber an die sehr spezielle Struktur der Matrix gebunden. Um circuito prático de um codificador pode ser obtido tanto a partir da utilização de portas lógicas como a partir de uma matriz de diodos. O processo que utiliza uma matriz de diodos é o mais simples de entender pela sua própria estrutura que visualmente corresponde a própria tabela verdade.
